Do you know when to replace your tires? The good news is gauging the health of your tires isn’t as complicated as you might think. In most cases, figuring out when it’s time for a tire replacement only requires a quick look with a keen eye and maybe the help of a copper penny. You need to know what portions of the tires to look at and what the key tire replacment indicators are. In this guide, we will provide you with all the knowledge you need to accurately assess your tires, determine if they need to be replaced and when, as well as some tips for picking new ones!
Here are the three key concerns related to tire replacement:
In this tire replacement guide, we’ll answer these questions and beyond so that you can feel confident you’re replacing your tires with the best choices for your driving needs, local climate and vehicle safety.
The most common question people ask is “How often should you replace your tires?“
Generally, there are two different factors that impact when to replace tires: wear and age.
Tire Wear: All tires eventually begin to experience wear. How the tire wears can be a indication of an issue with your alignment or tire pressure. Tire tread should wear evenly across the whole tire rather than on the inside or outside of the tire. The wear on your tires will happen regardless of how good of a driver you are, although it can be accelerated if you don’t take proper care of the tires.
Tire Age: Tire aging occurs when components of the tire, including the rubber, begin to change over time. This can happen due to environmental impacts and storage conditions, as well as the amount of usage the tire sees when being driven, or the tire sitting with no use.

Of course, unless you’re a tire expert, it can be difficult to know exactly when tire wear and age indicate that a tire is no longer safe to drive and needs to be replaced.
If you’re wondering, “How do I know when my tires expire? “ A better question is “How old are my tires and when should I change them?” To answer that question, it’s time to learn how to read your tires!
Every tire has an indication that states when it was made, down to the week and year. This can help you answer the question: how often you should change your tires – even if you’re not an expert on the subject.
Industry standards say you should replace passenger and truck/SUV tires on average at 6 years and before 10 years of age. The timing depends greatly on how the tires have been used and the weather extremes it has been subjected to. How a vehicle has been stored can also impact when a tire needs to be replaced. If your tire passes the penny test, and a visual inspection does not show any cracks or damage, but the tire is 6-10 years old, the wisest course of action is to have them inspected by a tire shop to determine if you need to consider replacing them.
Knowing how often to replace tires isn’t just about taking good care of your vehicle and preventing expensive mistakes. Tires are an extremely important part of your vehicle’s safety.
Worn or old tires can lead to a variety of problems, including:
Additionally, uneven wheel alignments and balance problems will not only cause irregular and premature tire wear, they can cause expensive problems for your vehicle, leaving you dealing with a hefty car repair bill in the future.
Each year, roughly 11,000 tire-related wrecks occur on the road. Don’t blow off tire maintenance as something only “car people” do. Every driver on the road should are about the health and safety of their passengers and vehicles.
Many people ask “How long do tires last on average?“
The problem is, there’s not a set answer to that question – due to the variety of factors that can lead to a necessary tire replacement.
These factors include:
Every driver faces different conditions and cares for their cars differently. The bottom line is that you need to be aware of your own driving habits, environment, and tires to ensure you’re replacing your tires when necessary.
The following tips will show you how to tell if tires are worn and need to be replaced soon.
Although it is always best to seek professional help with tires, these signs will indicate that you should begin researching new tires for your car.
If your tires have been worn down unevenly, you may feel a vibration in the steering wheel when driving. Vibration can also be caused by poor alignment so it is important to have a tire professional determine the cause of the vibration.
Moisture can leak into the tire, causing the steel parts to rust. Lodged items can weaken the area of the tire and possibly lead to dangerous blowouts if not dealt with in a timely manner.After you have figured out when to change tires, you’ll find that selecting replacement tires a bit of a process. You’ll need to start by assessing your driving habits, the types of terrain and seasons you will be driving in, to determine what you need in a tire. You should also evaluate how well you feel your current tires performed in longevity, handling, ride, noise and any other category you have noticed.
After that, you’ll be able to match your driving style to the perfect tire type. To help jumpstart your research, here are a handful of the most popular tire categories, seasonal applications, and the features that make them great fits for particular drivers’ needs.
They can be used all year round and offer excellent traction and performance in all weather.Before you decide which tire you need, think about what kind of driving you do. If you drive primarily on the highway and city streets, you may need a highway or touring tire. On the other hand, if you typically drive on back roads AND need on-pavement capability, an all-terrain might be your best bet.
If you face severe winter weather during certain points of the year, you will likely need to upgrade to a tire that can handle those conditions.
First pick the category of the tire to fit your driving needs, then decide on the season that best suits the climate you live in.
The NHTSA has rated more than 2,400 tire lines. You can use the official NHTSA website to check out the details on specific tires.
The treadwear grade rates how well a tire compares to others in a specific test. A tire with a grade of 3000 wears three times as long as a tire that only has a grade of 100. However, you should keep in mind that different driving styles, road conditions, and levels of maintenance can also impact treadwear.
This refers to the tire’s ability to stop on different kinds of surfaces, including asphalt and concrete. AA is the best rating a tire can receive, followed by A, B, and then C.
The temperature rating indicates the tire’s resistance to heat. A is the highest rating, followed by B and then C.
Some people, in an effort to save money upfront on the tire replacement cost, turn to old (used) tires as replacements. However, this can be a risky strategy, even if it does save money initially.
Here are some of the issues you can face when buying second-hand tires as replacements.
Last but not least, people generally don’t pay attention to their spares as they decide when to get tires replaced. Because the spare isn’t used much, people assume that it doesn’t experience wear or tear and that it doesn’t need to be replaced.
However, even spare tires need to be replaced after a certain amount of time. Be sure to check the date of production on the spare before deciding not to replace it. If you’re not sure how to check the date of your tire, refer to our post on DOT Date Code.
Don’t forget to pay attention to visible kinds of age as well. Just because a tire hasn’t really been used doesn’t necessarily mean it stays protected from cracks or cuts, as well as other problems that come with age including:
Whether a tire has been driven or not, its lifespan can be affected by its storage condition and treatment. If you know you will be parking your vehicle for a period of time, it is a good idea to protect the tires from sun and freezing temperatures, move the vehicle periodically to prevent flat spots, and even jack the vehicle up safety to prevent damage.
If you are storing winter or summer tires, it is best to store them in a cool, dry location away from sun and other weather elements.
To sum things up, here’s a list of the most frequently asked questions, as well as some brief answers to steer you in the right direction when replacing your tires.
Although this answer does depend on a number of factors including the type of car, your driving style, etc., there is an average estimate for how often you should change your tire. In general, most vehicles travel about 15,000 miles per year, which equates to around 45,000 miles every three years. If you to take into account the tire mileage warranty and amount you drive over the course of a year (over 15k miles), this will give you a good indication of how often you will need to replace your tires.
This is a topic of much debate. However you will find most vehicles, regardless of if they are front wheel drive or all wheel drive, will wear the tires on the front more rapidly than the rear.
The front tires are responsible for the steering, acceleration and braking, while the rear wheels typically just follow. Most vehicles also have most of their weight on the front of the vehicle, causing the front tires to handle more load than the back tires.Since the wear and tear on the front and back wheels can be different, the answer to which tires wear faster, is typically the front tires.
All-wheel drive vehicles must have all four tires replaced at once. You don’t have the option to replace just two at a time.
Because tires wear unevenly front to back, regular rotations will allow you to get longer use out of your set of tires by wearing the tread more evenly. Front tires will wear the outside edges down more quickly, so rotation allows you to always have the most tread on the outside of the tire. Not rotating will result in one set of tires wearing and likely needing to be replaced sooner than the other set.
First things first: check your vehicle’s owner’s manual to see if it has a recommended rotation scheme.
Tires should be rotated roughly every six months or every 6,000 to 8,000 miles. A good rule of thumb is to rotate the tires every other time you get an oil change.
Placing a penny head into the grooves of your tire can help you determine if the tire needs to be replaced soon. If you can see the top of Lincoln’s head, your tires are likely shallow and worn. Use this as an indication of when you should have a tire professional examine the situation.
If you are replacing only one pair of the tires on your vehicle, these new tires will have a deeper tread depth. Be sure to install the new tires onto the rear axle for better control when driving on wet and winter roads.
Ideally, you need to replace two tires with matching new ones. However, the most important thing is to install tires with similar performance features. For example, you should never put two high-performance tires with two touring tires.
Generally, it’s smart to replace tires in pairs (both in the front or in the back). Although replacing all four at once is the easiest, if you need to save money, you can do one pair at a time. If you’re wondering “can I replace just one tire?“ the answer is typically no. The difference in tread depth and stance can throw off your vehicle’s performance.
Most tire sellers would likely recommend that you avoid mixing tires from different categories. They can be different brands, as long as the internal construction and size are the same – but pay close attention to the stance of the tires and be sure they are very closely matched
Nope! Just make sure that all of the tires are evenly matched and appropriate for your vehicle and your driving habits.
It’s difficult to give a firm answer to this question.
Generally, most tires typically last for three to five years. That’s when roughly 12,000 to 15,000 miles are put on the car annually.
The best things to do to make your tires last as long as possible are:
Once you get your new tires installed, take it easy on the road for a while to break the tires in. New tires may feel different than the tires you replaced, since they are likely performing better than a worn tire, and have the latest technology.
Also, if you changed categories of tires, you might experience a big change in the feel of your drive. For example, switching from an highway to an all-terrain tire might change the roughness and noise of your drive, as well as your fuel consumption.
Deciding when to replace your tires is an important decision, both for the safety of your vehicle and that of others. Use the above guide to steer you in the right direction and help determine exactly when you should make the switch to brand new tires.
Additionally, deciding what to replace is important. You can increase (as well as decrease) the comfort, fuel efficiency, noise, tread wear, or other aspects based on the decisions you make with new tires.

It may be tentative, but tires do have an expiration date. There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left. How do you know how old your tires are? There’s a code on the sidewall that you can read about here. Wear is a far more straightforward consideration: Tiremakers and safety advocates say a tire is worn out when its tread depth reaches 2/32 of an inch.
That’s all fine, but what most car owners want to know is how long to expect a set of new tires to last before they need to be replaced.
“I wish it were simple to say how long each tire might last, but tires are different,” said Dan Zielinski, a spokesman for the U.S. Tire Manufacturers Association (USTMA). “Some tire manufacturers offer a warranty as high as 80,000 miles or more, reflecting confidence in that particular product’s longevity based on its engineering, technology, and design. Other tires may be built to provide 30,000 miles of service.” Or less; some high-performance tires on cars driven aggressively will be worn to the 2/32-inch point without ever seeing 15,000 miles, but those are extreme cases.
The average American drives between 14,000 and 15,000 miles a year, according to data from the Federal Highway Administration.
Zielinski said that, if you’re kind to your tires—that is, you aren’t constantly peeling out at stoplights and you properly maintain them—most new tires on the market today will last about 60,000 miles. For what it’s worth, the USTMA did a review of several thousand recently scrapped tires and found that most were three to four years old. There was no way of telling how many miles were on those tires, but it’s easy enough to multiply four years by 15,000 miles annually to confirm the rough approximation of tire durability.
If you want to figure out how soon you’ll wear out the tires on your car, Zielinski said it would be a good idea to start by determining how many miles you drive each year. Divide the number of miles on the odometer by how many years you’ve owned the car (starting, obviously, from when you first got the car and accounting for any mileage it had on it at that time). Then you can compare that with any advertised warranty on the make and model of the tires and figure out how many years of service to expect.
If you live where winter tires are advisable and swap those onto the car for some months of the year, your regular tires will get less use and will endure for a longer period of time, but remember the caveats about tire age.
Zielinski also noted that if you hit the wear bars at 50,000 miles on a set of tires with a 60,000-mile warranty, for example, tiremakers that offer such coverage will typically prorate the price of a new set. In this example, you could expect a discount on the new set equal to one-sixth their price, or about 17 percent. You might not get it, though, if you decide to change brands.

In general, the best way to preserve the life of your tires, and keep yourself and your passengers safe, is to maintain them properly. Here are some tire basics and maintenance tips:
Tread
A tire is considered unsafe, and should be changed, once its tread is worn down to 2/32 of an inch, according to the National Highway Traffic Safety Administration (NHTSA).
Many tires have tread-wear indicators, which are little bars in the tread that show when the tire is worn down to replacement level. These will start making noise to alert the driver that they need attention. You can also use a penny: NHTSA recommends putting the penny in the tread with Abraham Lincoln’s head upside down and facing toward you. If you can see the top of Abe’s head, it’s time for new tires.
Pressure
To ensure even wear, tiremakers and auto companies recommend that vehicle owners check their tire pressures monthly. The pressure should be at the vehicle manufacturer’s recommended level, which is usually found in the car or truck’s doorjamb or in the owner’s manual. One quick and easy way to check tire pressure is with a handheld tire-pressure gauge, which you can find starting around $10 at an auto-parts store. Tire shops will often check the pressure for you. Some gas stations have digital readouts as part of their air pumps; these are not always accurate, though.
It’s best to check the pressures when the tires are cold, meaning that they have not been driven on for several hours. So you’re better off checking them at home after the car has been parked overnight.
Balance and Alignment
Tires need to be round, and the tire/wheel combination needs to be balanced. Tire shops and mechanics will use a balance machine, which spins the wheel to see where high and low spots are and detects any imbalance. The tire shop will then add weights, which are hammered onto the wheel, to balance them. These shops can also make make sure your wheels are aligned to keep the car tracking straight, which also reduces tire wear.
Rotation
Rotating your tires can help prolong their lives.
For front-wheel-drive vehicles, the tires in the front will wear more quickly and can be swapped with the rear ones. The inverse is true for rear-wheel-drive cars and trucks. All-wheel-drive models, too, may need rotation. Most owner’s manuals contain a recommended pattern for rotating tires to spread the wear evenly. The USTMA recommends tires be rotated every 5000 to 8000 miles.

7 rubber signals: what the tire says about car problems
How do you know when tires are completely worn out and it's time to change them? Everything is simple. For summer tires, the limit is 1.6 mm of residual tread depth, and for winter (or all-season tires used in winter) - 4 mm. Modern summer tires can travel from 40,000 to 70,000 km, depending on driving style and vehicle characteristics. An average motorist rolls such a mileage on summer tires in 2-3 seasons. Moreover, wear implies not only a decrease in tread depth.
For millions of cycles of deformation, the strength of the carcass and its adhesion to the layers of the rubber compound are violated. In short, every 2-3 years you should buy a new set of tires.
In case of irreparable damage to one of the tires and a relatively high total mileage of the kit, it is also worth considering replacing it. Well, or about buying at least a pair of new tires, which, for any type of drive, should be installed on the front axle. We put two tires back - the most decent of the remaining ones.
Many motorists drive only a few thousand kilometers a year. This does not mean that the tires will serve you for several decades. According to Russian requirements (GOST 4754-97), the service life of passenger car tires is 5 years from the date of manufacture. And for example, Continental recommends that all car tires (including the spare tire) older than 10 years old should be replaced with new ones.
Therefore, with small runs, you can navigate for ten years. The date of manufacture of the tire is indicated on the sidewall. Usually it is an oval with four numbers. The first two are the ordinal number of the week in the year, the last two indicate the year.

Tires should be rotated periodically in accordance with the vehicle manufacturer's recommendations - information on this can be found in the owner's manual.
We can advise you to carefully use the tires and, most importantly, to store them correctly in the off-season. First of all, during storage, it is important to exclude direct sunlight from hitting the tires, which greatly age the rubber. Tires without rims should be placed vertically, and stacked on rims.
And before installing tires on a car at the beginning of the season, evaluate their condition.
There should be no cracks in the tread and sidewalls. The tire should not be dry, it should remain rubbery and not look like baked plastic.

Driving on badly worn tires - will I be fined or not?
Winter tires have a much shorter life span. They almost always fail due to the wear of the treadmill, because the tread of a new tire is 7–8 mm, and only 3–4 mm remain working height. If the tires are studded, then with such wear there are very few metal elements left, and the tire will not provide adequate safety when driving on a winter road. However, not only spikes, but also Velcro, with such a degree of wear, also lose most of their capabilities.
The real life of winter tires rarely exceeds 30,000 km. "Bald" winter tires without studs can be re-rolled in summer, but their grip on hot road surfaces will be very poor. This must be taken into account, especially when braking.
***
So: tires that have not yet worn out along the tread (that is, up to 1.6 mm tread depth for summer tires, 4 mm for winter tires) are changed either ten years after the date of issue, or when the rubber layer cracks tires or damage.

The first copies could not be called reliable. They often burst and torn. For almost two centuries of its history, car tires have been constantly improved and modern specimens are far superior to their ancestors, both in design and in terms of service life. But nothing lasts forever, and car tires are no exception. Sooner or later they will serve their purpose and will need to be replaced. The service life of automobile tires is the period during which the manufacturer guarantees the possibility of using tires for their intended purpose and is fully responsible for any inconsistencies in performance and resulting product defects. Car tires, according to manufacturers, last up to ten years. But in practice, they have to be changed approximately every 5-6 years, and sometimes even more often, which depends on many factors.
When assessing the life of tires, it is also necessary to take into account the mileage of the car (since each motorist drives differently, some 10 km a day, and some all 100). According to the accepted rules, the mileage standards for car tires are:
1. For passenger cars (carrying capacity up to two tons) - 45 thousand kilometers.
2. For trucks (carrying capacity from two to four tons) - 60 thousand kilometers.
3. For trucks (carrying capacity from four tons) - from 65 to 70 thousand kilometers.
Good tires are the key to a safe ride. But even the best rubber eventually wears out and loses integrity. Therefore, the driver should always monitor the degree of tire wear. You need to keep track of both summer and winter tires. Sometimes the service life of tires may not even reach five years, which, as already noted, is due to many factors that we will consider further.
So how do you know in advance when a car tire is nearing the end of its useful life?
1. If the tire tread is worn down to the level of the jumpers between the tread, then the tires have served their purpose. You can determine the degree of wear by eye or with the help of tools. To measure the tread height, use a ruler with a special depth gauge. For summer tires, this parameter should be more than 1.6 mm, and for winter tires - more than 4 mm. If these parameters are less, you should think about replacing tires. In case of uneven wear over the entire surface, measurements should be taken at the most worn area.
2. On the surface of some tires there are numbers of different depths. And you can judge the degree of wear by how many numbers are visible at the moment.
3. If the car has studded tires, then the need to replace it can be judged by how many studs are left on it (if less than half is left, it should be replaced).
4. Small cracks on the sidewalls of a tire indicate the aging of the rubber and are a harbinger of its imminent replacement. But deep cuts on the sidewalls are an alarm signal for an immediate replacement of rubber.
5. Swollen sidewalls (the so-called “bulges”) appear due to the rupture of the cord layer and indicate the need to replace tires (sometimes “bullets” occur on the inside of the wheel, so you should always be very careful about their inspection).
If you find something similar, then it's time to think about replacing tires. And to confirm your fears, the right thing to do would be to contact a specialist master who accurately diagnoses the condition of the tires.
Car tires are of different types, depending on the season for which they are intended:
1. Summer tires.
2. Winter.
3. All season.
Tires are made of different rubber for different seasons.
Summer tires are made of harder rubber than winter or all-season tires. Therefore, their service life will also be longer. As for all-season tires, they are not recommended for use in regions where the temperature in winter is much below zero , as they will not live up to your expectations and will last a very short time.
According to manufacturers, the service life of car tires ranges from seven (for winter) to ten (for summer) years. But one should not blindly believe such statements. The fact is that many factors influence the service life of car tires, including:
2. The quality of the road surface, which is far from ideal in our country.
3. The quality of car rubber greatly affects the life of tires. Cheap Chinese rubber will last much less than rubber from well-known brands (the service life of Chinese rubber is about two seasons, and branded rubber is about seven). But a famous brand is not a guarantee of success.
Indeed, very often fakes are sold under the label of well-known brands, and they, a priori, cannot last for a very long time (during the purchase, be sure to remember this aspect and choose wisely).
4. Various mechanical damages (for example, cuts, bumps after impacts, deformations due to emergency braking, traffic accidents, etc.).
How to determine the causes of tire wear? There are many reasons for tire wear. And this is not only the gradual erasing of the tread when moving on the road (in accordance with the mileage for which they are designed). It is not difficult to determine the causes of wear (this is done by the surface of the tire and the tread pattern). Let's consider several options.
1. If the outer edges of the tire are worn an order of magnitude more than the central part, then the tires were underinflated. And if, on the contrary, the central part is more worn than the outer edges, then the pressure was excessive.
2. If the tread edges are worn on only one side, then the camber angles have been violated.
3. Uneven tire deformation indicates the driver's addiction to extreme driving with hard braking.
Summing up, it is worth noting that manufacturers, indicating the life of their tires, are guided by ideal conditions. And each motorist must independently predict these terms for himself, paying attention to the considered aspects.
Tire life depends on the mode of use, storage conditions and other factors. But it is impossible to accurately calculate this value, since there are a lot of variables in this equation. In order for car tires to last as long as possible, it is necessary to take care of them regularly and make sure that they are not damaged.
Recommendations on how to extend the life of car tires:
1. It is necessary to do a timely technical inspection of the entire car, including tires.
